Examples of charva.awt.event.ScrollEvent

charva.awt.event.ScrollEvent
A ScrollEvent is posted on the event queue by a scrollable object such as a Table, when its state changes in such a way that it may need to be scrolled (if it is contained within a ScrollPane).

  Toolkit term = Toolkit.getDefaultToolkit();
  EventQueue evtqueue = term.getSystemEventQueue();


  // First scroll the list DOWN so that index 0 is visible.
  evtqueue.postEvent(
          new ScrollEvent(this, ScrollEvent.DOWN, 
    new Point(0, 0)));


  // Then (if necessary) scroll it UP so that the specified index
  // is not below the bottom of the viewport.
  evtqueue.postEvent(
          new ScrollEvent(this, ScrollEvent.UP, 
    new Point(0, index_)));
    }
